Well, this one has not been fully approved by the FDA past an emergency use authorization. And it is being required of an age group with a 99.8% survivability of the virus. Put the two of those together and it is asinine to require them all to take it.
Additionally, the vaccine does not keep you from catching the virus, it only makes it less worse if you do. So if they can still spread with the vaccine, they rarely die from it, then what is the point of forcing them to take it. The virus is more deadly for older people but if they have the vaccine they are good to go.
The only rubes are people who think that Johnson and Johnson and companies like it won't hide stuff like asbestos in their baby powder for 60 years in order to make a buck. People should have a right to refuse this shot until it is backed by long term research, this is particularly true for people who are likely to be impacted by the virus in a similar fashion to the flu (i.e. young adults)
